In third place, with eight percent of the vote, was former Dallas mayor Tom Leppert. Fourteen percent of respondents said they remained undecided at this point in the race.

The latest poll is a stark contrast to the last poll of Republican voters in Texas. Dewhurst was the clear favorite with 41 percent support in that poll, conducted by Public Policy Polling in mid-September. Cruz came in second with 14 percent of the vote and 34 percent of respondents were undecided.
